reproduction. If a passive speaker is
connected, that too will operate in mono
mode.
4.3 Deactivating the
LED display on an IR
equipped speaker
Should the LED indicators on the speaker
not be required the following procedure
will disable them:
• Remove the speaker grille (using a
small hooked tool and easing the grille
off) to expose the driver and IR sensor
electronics.
• Locate the jumper labelled LEDs OFF in
the IR sensor printed circuit board.
• To extinguish the LEDs remove the jumper
and reposition on one pin only (for safe
keeping).
• To re-enable the LEDs simply reposition
the jumper across both jumper pins again:

Setting the keypad to
enable local input
toggle
The factory default setting for the keypad
is for the local input toggle to be disabled.
If therefore, you plan to use a local input
and wish to select it via the keypad you
will need to enable this feature.
To set the keypad to this mode:
• Ensure that the keypad is operating
normally, put the zone into standby – red
LED ON.
• Depress the
O
and
VOL+
keys on the
keypad simultaneously (both together at
exactly the same time). Hold briefl y until
you see the status LEDs fl ash.
The LEDs will fl ash to show you the new
sequence which is Blue > Green > Blue >
Green > Red (Mode 2 Local enabled).
To revert to the original Mode 1 (local
disabled) repeat the process and the LEDs
will fl ash Red > Blue > Red > Blue.
4.5 Changing addresses
for sub-zones and
expanded zones
Note:
It is normally not necessary to
change this address.
The only time that the address needs to
be changed is for one of the following
reasons:
• Where the infra-red commands can be
received by more than one zone at the
same time (if doors are open and the
zones are next to each other).
• When a sub-zone is specifi ed
(independent volume).
For expanded zones, there is normally no
need to change the address, as there will
be a desire for each of the speakers in the
expanded zone to work in unison.
The only modules that need addressing
are the speaker, keypad, and handset.
However the speaker will automatically
adopt a new address when it receives
commands to do so from either a keypad
or handset.
If you want the sub-zone to operate in
synchronism with the main zone leave
everything as it was shipped.
Note:
Ensure that all comments in section
5.1 of the
Planning Guide
are observed
when fi tting expanded zones.
